DNS trouble when creating account with subdomain

[monsignore]

Hi !

I have a big problem with DNS propagation when creating a cpanel account with a subdomain on my server.

for exemple.

i have domain.com an more than 1500 subdomains directly insered in the account and no problem. All DNS (2nd and 3rd) are ok and the zones are dupplicated.

xxx1.domaine.com
xxx2.domain.com etc.

If i create an account with a subdomain on the domain

zzz1.domain.com, the dns zone DOES NOT dupplicate on the secondary dns servers !

And this is a great problem since the sites are not accessible.

Did I missed something when creating the account ?

I precise that dns config for the account zone is correct....

Thanks
